Issues with back buttons

Hi there,

more questions (i’m nearly finished i promise!)…

My back buttons don’t seem to be working properly… have i got the syntax right, i’m using the Tab app…

Firstly, in index.html…

 <body ng-app="listings">
    <ion-nav-bar class="bar-assertive">
      <!--Template views go here -->

then, my tabs.html…

<ion-tabs class="tabs-icon-top tabs-assertive">
	<!--Home tab setup --> 
	<ion-tab title="Home" icon="ion-ios-home-outline" href="#/tab/home">
		<ion-nav-view name="home-tab">
	<!--Listings Tab Setup --> 
	<ion-tab title="Listings" icon="ion-ios-list-outline" href="#/tab/list">
		<ion-nav-view name="list-tab">
	<!--Leaderboard tab setup --> 
	<ion-tab title="Leaderboard" icon="ion-ios-people" href="#/tab/leaderboard">
		<ion-nav-view name="leaderboard-tab">


and then, a tab for the list that i’m displaying…

<ion-view view-title="Available Listings">

  <!-- **Subheader Starts here --> 
  <div class="bar bar-subheader item-input-inset bar-light">
    <label class="item-input-wrapper">
      <i class="icon ion-search placeholder-icon"></i>
      <input type="search" ng-model="query" placeholder="search" />
  <!-- **Subheader ends here -->

  <!-- **Content section starts here, repeat through list of properties --> 
  <ion-content class="has-subheader">
  <ion-refresher pulling-text="Pull to Refresh" on-refresh="doRefresh()"></ion-refresher>
    <ion-list> <!-- took these out of here show-reorder="data.showReorder" show-delete="data.showEdit" -->
      <ion-item class="item-thumbnail-left item-text-wrap item-icon-right" 
      ng-class="{'star' :}"
      ng-repeat="item in listings | filter: query" href="#/tab/list/{{ }}">
        <img ng-src="img/{{ item.mobile_image__c }}" alt="Image" />...etc

there’s a couple of problems here… firstly, the view title isn’t updating when i’m moving between views correctly and my back buttons aren’t working also. From reading i think i’m right in only having the ion-nav-back-button directive on the index.html page, but not sure why it isn’t working…

can anyone spot my mistake??
